INTERNAL COMBUSTION ENGINE.

WW-aw in T 0 all whom it may concern:

Be it known that i, Jenn EV. Burners", a citizen of the United States, residing e- Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in internal-Combustion Engines, of which the following is a specification.

This invention relates to internal comhus tion engines and is more particularly directed to an improved type of. valve structure. Specifically, this invention is considered h me as an improvement over a portion the valve structure shown in my (Bo-pending application, Serial Number F5160.

The main object of this invention resides in a structure whereby a pocket construc tion is provided into which the intake gases ing the normal operation of the engi structure is also such that these indrawn gases may be heated before they are 1ntro duced into the engine cylinder, thus insuring more perfect vaporization.

The preferred embodiment oi .nrv inven tion is shown in the accompanyingsheet drawings, in which similar eha icters reference designate corresponding parts, and in which:

Figure 1 is a central vertical section through one end of an internal CO1 bastion engine showing my improved valve in its applied position, and,

Fig. 2 is a horiiontal se the intake and exhaust Fig. 1.

In these several views, the engine cylinder is designated by the ref' rence numeral 1, this cylinder being provided. th a water jacket 2 and a head 13 tion 3 in which exhaust port l and the intake port located. Between these two ports or pirsageways there is formed common passage way 6, into which the valve ructure ihe entire engine is mount d. This val structure comprises a hollow sleeve valve closed at its rear end as shown a" provided at this closed end rack 9, hy,means oi which rotated by mecl 'anisin not the ports -land 5 in t r pro; This sleeve valve is also provided with a slotted opening 10, which openio" when positioned opposite either the po 5, forms a means of communication between passage these p its and the interior of the engine, this communication being governed, however, by the puppet valve 11 shown mounted upon the inner end oi a rage member 12,

cage member remains in a stationary position and is provided with ports 13 and opposite the exhaust and intake passageways; i and 5 respectively will he noticed that the sleeve valve is mounted between this cage member and the engin and in this manner cuts oil or completes the communication between these passages and interior of the common 6. li ithin this ca meniher there is formed a pocket structme by means of th wall 1", this pocket structure being open its front end as shown at 16 and being of a size which will prevent the wasting oil an unneccssaw amount of fuel. after the same is drawn therethrough. During the the puppet valve is operated to f 5 10 will be adjacent either intake passageways l or stroke of the piston, this w l lie in a position opposite thereby establishing corninterior of the moon of this interior port-.on of en materially re laced. howf the wali if T drawn in which cylinder, w l =hin space beneath the u valve turns to l the oassa."

e connnunication l L space what known as de Because of the small vohune, there is small porof the which remairin this pocket, asin ch there is o one or i o the vapors will we intake passagowa Enter the firing of the envalve again opened h r shown, to allow the escape oi exhaust g ses, but because the space hcthe i5 is a dead space, these 0X- passages will not connninn le with the fases, out will. pass directly out through toe exhaustmssan ewa v 42. The pa "age 31 the exhaust gases wil also heat up this wall 25, thereby heating the passageway through which the intake must pass and in I CC? 11 ration of the engine, the valve- Ill) this manner cause their more perfect volatilization. It will also be noted that the space above the partition wall 15 is larger than that beneath it and this is so arranged because the volume of the gases after they are heated, is considerably more than when they are comparatively cool. Therefore, this allows the free entrance of the comparatively c001 gases and also the free entrance of the hot and also expanded gases.

What I claim, is:

1. In an internal combustion engine providedwith intake and exhaust passages, a common passage leading into the engine c vlinder and communicating with both the intake and exhaust passages, a (age member located within said common passage and provided with a valve seat at its inner end. a hollow valve supported by said cage member movable to bring the engine cylinder into or out of communication with said passages, a pocket structure in said common passage in a position over the intake passage and open at its front end to permit the flow of gases thcrethrough into the engine cylinder,

and a valve working on the valve seat of said cage.

2. in an internal combustion engine provided with intake and exhaust passages. a common passage leading into the engine cylinder and communicating with both the intake and exhaust passages, a cage member located within said common passage and provided with a valve seat at, its inner end, a hollow valve supported by said cage member and movable to open or close communication between the engine cylinder and said passages, a pocket wall located within said common passage between said intake and exhaust passages to form a pocket for the incoming gases, and a valve workingon the valve seat of said cage.

3. In an internal combustion engine pro-,

vided with intake and exhaust passages, a common passage leading into the engine evlinder and communicating with both.the intake and exhaust passages, a cage membei located within said common passage and provided with a valve seat on its inner end, a hollow sleeve valve supported on the exterior of said cage member movable to open or close the communication between said passages and the engine cylinder, a pocket wa'll within said cage member interposed between said intake and exhaust passages and open at its inner end, and a primary 'alve working on the. valve seat of said cage.

In testimony whereof T allix my signature in presence of two witnesses.
